I had the same problem. You can't tell by just looking at it without 
disassembling it. I rebuilt the mode switch, but it still didn't cure the 
problem. Put in a different mode switch, "used but supposedly working" ... no 
improvement. I hooked up a small piece of clear hose to siphon on by mouth 
and used it to see if I could tell if the actuators worked... the one I 
tested did. And see if I could detect any difference in the mode switch, 
which I could. I could say "crude but effective," but for the fact I still 
couldn't cure my problem. So we'll leave it at "crude." Fortunately I was 
scheduled for service at PJ Grady. (Exhaust manifolds, etc.) Rob combined 
parts from both mode switches to make one good one. Checked and glassbeaded 
the rusted (rheostat?) in the motor area, and redid my fuse block. (Oh yeah, 
high fan speed wasn't working either. Arghhh!) And he noticed a loose wire 
in back of the switch. I have big hands, and no eyeballs on the end of my 
fingers, so that doesn't help. Rob fixed all that, and now it works great. 
You can always send your mode switch to Rob or your favorite D vendor to 
check out and either rebuild or replace. Now my D sounds great, defrosts 
great... it was worth the wait!
